Question 1

ABC Manufacturing uses Dynamics 365 Business Central to manage their inventory. You need to create a report that shows the current quantity on hand for all items, but with the option to filter by specific item groups or locations dynamically chosen by the user.

Available Data Items:

Item (Item No., Description, Item Group)

Location (Location Code, Description)

Inventory (Item No., Location Code, Quantity on Hand)

Which approach is most efficient and flexible for achieving the desired functionality using queries?

Options :

A : Use record variables to store the user-selected item group and location code, then join them with Inventory in the query based on the selected values.

B : Create a temporary table containing all inventory data and then filter it dynamically in the report based on the user-selected item group and location code.

C : Use a single query with optional filters based on the Item Group and Location Code fields, allowing the user to choose whether or not to apply them.

D : Create separate queries for each possible combination of item groups and locations, and then dynamically switch between them based on the user-s selection.

Answer: C

Question 2

A developer needs to set up a development environment for Business Central online on their local machine. They want to leverage Docker containers for isolation and portability.

Which combination of tools and configurations should they use to achieve this?

Options :

A : Install Visual Studio Code, the AL extension, and configure Docker with the official Microsoft Dynamics 365 Business Central developer container image.

B : Install Visual Studio with Dynamics 365 Business Central development tools, set up a local SQL Server instance, and configure Docker with a custom-built container image containing necessary components.

C : Utilize the Business Central web client developer tools within the online environment, connect to an external SQL database, and develop extensions directly in the browser.

D : Deploy the development environment onto an Azure virtual machine with pre-installed tools and configurations, utilizing Visual Studio and SQL Server Management Studio.

Answer: A

Question 3

You want to configure telemetry to track the performance of your extension's user interface (UI) elements. Which telemetry features can you leverage for this purpose?

Options :

A : Application Insights custom metrics and page views.

B : Business Central built-in performance counters.

C : Azure Monitor Application Insights custom traces.

D : Microsoft Power BI integration with Business Central telemetry.

Answer: A

Question 4

You are writing unit tests for a function in your Business Central extension that interacts with a third-party API. You want to isolate the unit test from the actual API to ensure it tests the core logic of your function.

Which of the following techniques is the most appropriate for mocking the external API in your unit tests?

Options :

A : Use the "TestPage" concept to mock the API behavior within Business Central.

B : Write a separate AL codeunit to simulate the API responses.

C : Leverage the built-in "TestMocks" framework provided by the ALTest framework.

D : Use the "Record Replay" functionality to capture responses from the real API and replay them in the test.

Answer: C

Question 5

A developer is debugging a Business Central extension in Visual Studio Code and has paused execution at a breakpoint. They want to examine the values of variables and expressions within the current context to understand the code's behavior.

Which debugging tool in Visual Studio Code should they use to view these values?
